Power supply unit with 80 PLUS Gold efficiency and powerful 45 A single rail
The Seasonic G12 GC-550 is a powerful power supply unit and, with its 550 watt total output power, also supplies high-end gaming PCs with plenty of power. The powerful 12-volt rail delivers a whopping 45 amps and is also certified with 80 PLUS Gold. Seasonic consistently relies on high-quality electronic components, including LLC resonance converters.

The Seasonic G12 GC-550 with 550 watts provides a 24-pin, a 4 + 4-pin cable and an 8-pin connector, among other things, two 6 + 2-pin PCIe connectors and three SATA, three 4-pin Molex connectors ready. With this variety of connections, high-performance systems can be implemented. The black power supply fits perfectly into any case.

Automatic fan control
The built-in 120 millimeter fan has a smooth-running slide bearing, which ensures extremely smooth running during operation and a long service life. Seasonic's automatic Smart-and-Silent-Fan-Control-Technology (S2FC) ensures that the fan only starts when the load is 50 percent. This is particularly noticeable in the noise development and the maximum possible cooling performance, depending on how much the power supply is currently being used.

It almost goes without saying that the Seasonic G12 GC-550 power supplies have all the necessary protective circuits that modern high-end models should offer. The load regulation operates with an extremely low voltage tolerance. In addition, Seasonic grants a full five-year manufacturer's guarantee.
